Amino alcohols which have the physical and chemical characteristics of both
alcohols and amines in one molecule . The amino alcohols are highly useful
materials for a wide variety of applications.
•Chemcial intermediate application
The amino alcohols are useful
intermediates for a wide variety of synthesis. Many chemical reactions are
common to the amino alcohols to form following examples;
- amides and amide esters with carboxylic acids and organic
acid esters
- amino acids by oxidation of the alcohol and
by hydrolysis of the amide
- diamines with nitro alcohols
- heterocyclic organic
compounds such as oxazoline by dehydration
- oxazolidine with aldehydes or
ketones
- oxazoline esters and diesters with three moles of an organic acid
- poly(amideester) with dibasic acid
- salts with
inorganic acids
•Emulsifier applications
Amino alcohols are used
for production of efficient anionic emulsifiers and nonionic polyethylene
emulsions. They appear in personal care products formulations and show better
base strength, lower neutral equivalent, and lower volatility than traditional
amine emulsifiers. Amino alcohols are used in personal-care products with the
neutralization function of acid raw materials. They
render resinous materials water-soluble. They provide
base strength values with low odor levels, good
water and alcohol solubility and color stability
in cosmetics.
•Coating application
The difunctionality of amino
alcohols makes them useful as raw materials in polymer applications in both
water- and solvent-based to increase the solubility of other components and
improve solution stability. They function as a pigment dispersion-aid dispersant
to enhance the wetting and viscosity stability. The salts of the amino alcohols
are also used in coating to improve the package stability.
•Corrosion
Inhibition application
Amino Alcohols maintain a constant alkalinity in the
boiling water flows and condensate not to form solid products which would impede
line flow. This function is applied for corrosion Inhibits. They are widely
employed in the preparation of water soluble cationic flocculants and ion
exchange resins which adsorb solid and colloidal particles by electrostatic
attraction. They are used for water treatment, metal treatmet and absorption of
CO2 gas.
•Catalyst application
The salts of the amino alcohols like not only
hydrochloride salts but also nitrate, sulfate, phosphate, and sulfonate salts
can be used alone or in combination with other catalysts for balanced curing
action with selected textile-resins.
•Biochemical application
In biological
field, amino alcohol structure is widely found in many drugs especially
antihistamines. Shingosine, the major base of the sphingolipids in mammals for
signal transmission and cell recognition is an amino alcohol. Amino alcohol
compounds are the starting materials in the preparation of beta-lactam
antibiotics, humectant for foods and cosmetics, flavouring agents as well as
many oral, injectable or topical pharmaceuticals. Amino alcohols are amine
buffers used in a variety of medications.
